To increase transparency around its processing of project review requests, Verra publishes the average processing times for various types of project review requests. Verra also provides stakeholders with target service-level agreements (SLAs) to establish clear performance benchmarks regarding project review times. Both SLAs and average processing times are available on the Verra Project Hub.

The SLAs differentiate between request type, program(s) used, and the complexity level factor of a given project review.

Review complexity is a factor that is based on a specific project’s individual characteristics and that impacts (1) the technical review and (2) the PRR technical review stages.

Review complexity impacts the technical review stages as follows:

  • The presence of one complexity factor increases the time for the regular technical review SLA(s) by a factor of 1.25 (resulting in a high complexity review).
  • The presence of two or more complexity factors increases the time for the regular technical review SLA(s) by a factor of 1.5 (resulting in a very high complexity review).
  • A review request for registration and verification approval of a grouped project increases the time for the regular technical review SLA(s) by a factor of 1.5 (resulting in a very high complexity review).
  • A review request for a Jurisdictional and Nested REDD+ program increases the time for the regular technical review SLA(s) by a factor of 1.5 (resulting in a very high complexity review).

Complexity factors apply to the following review request types for projects in all operational Verra programs:

  • Registration
  • Registration and verification
  • Verification
  • Crediting period renewal
  • Crediting period renewal combined with verification
  • Methodology change and requantification
  • Methodology change and requantification combined with verification

Review requests for projects in the Climate, Community & Biodiversity Standards (CCBS) and Sustainable Development Verified Impact Standard (SD VISta) Programs begin at high complexity. If any additional complexity factor applies to the same review request, it changes the complexity level of such a request to “very high.”

Current complexity factors are as follows:

  • Grouped project registration
  • New project description deviation
  • New methodology deviation
  • Use of two or more methodologies
  • Complex methodology (see below)
  • The inclusion of an SD VISta review request for an open a VCS project review request
  • The inclusion of a CCBS review request for an open VCS project review request
  • Joint CCB-VCS project
  • VCS project nested in a baseline/program registered with the Jurisdictional and Nested REDD+ Framework

Complex methodologies require additional resources and time for review or include certain interpretation challenges.

Any version of the following methodologies is currently considered “complex”. Verra will continually update this table.

Note: Review complexity is similar to review risk level. However, while review risk level determines review intensity, review complexity determines review duration.
